' IMPROVEMENT IN WRlNGlNG-MACHINES.

Specification forming part of Letters Patent No. 163,645, dated May 25,1875; application filed To all whom it may concern:

Be it known that we, CHARLES A. Ersnn- HART and EDMUND E. LAUER, both ofYork, in the county of York and State of Pennsylvania, have inventedcertain Improvements inGlothes-Wringers, of which the following ing is aspecification:

This invention consists in gearing for connecting the rolls at alltimes; in the manner of jointing the bearings of the upper roll; in theconstruction of the spring for exerting pressure upon the upper roll,and in the construction of the clamping-jaws, as hereinafter set forthand claimed.

In the accompanying drawings illustrating our invention, Figure 1 is aside elevation. Fig. 2 is a top-plan view. Fig. 3 is an elevation of theinner face of one of the lower eastings with the wall of the clamp-jawgroove partly broken away. Fig. 4. is a side elevation, partlysectional, of one of the bearings for the upper roll. Fig. 5 is a sideelevation of the upper-roll bearing, partly in section,

and part of the lower casting, showing the manner of jointing the two.Fig. 6 is a side view of the main clamp-jaw, and Fig. 7 is a partlysectional view, showing the arrangement thereof in the lower casting.Fig. 8 is a rear elevation of the adjusting-screw plate or jaw; and Fig.9 a sectional view thereof,

. showing the mode of attachment to screw. Fig.

10 is a top view at mm, Fig. 3, showing the arrangement of the head ofthe adjusting-screw plate in the lower casting. Fig. 11 is a plan viewof the connecting-links with the gearing in dotted lines. Fig. 12 is anedge view of one of the links with pinions attached. Fig. 13 is a planview of the other link.

Similar letters of reference indicate like parts in the several figures.

The letter A represents the lower casting, made with a hollow leg, 1, anL-shaped leg, 2, also hollow and grooved, and fenders 3 4. B is thelower roll, having its hearings in said casting. O is the bearing, ofcast metal, for the upper roll D. This bearing is jointed to the castingA by flanged ears a, placed on each side and fitting over gudgeons 12,extending from a projection on the casting A, as shown in Figs. 3, 4,and 5. The rolls are rotated by means of pinions c d on their shafts,which September 23, 1874.

are connected by stud-wheels cf. g is a plate or link for connectingpinions e f, said pinions revolving on arbors 5 and 6, projecting fromthe plate at right angles thereto. From the lower end of link 9 asimilar arbor or pin, 7, extends through the casting A and is keyed, andat the upper end a short stud, 8, projects into a plate'or link h. Thislink serves to con. nect the pinion f with pinion c, and has ahole in itto fit on the shaft of roll D. By thus gearing the rolls their rotationis not interrupted, for the pinion f will be carried along with theupper roll in its motions, and still preserve contact, and be in meshwith the other pinions, and by the use of the link connections, havingthe central joint at the pinion f, the gearing moves with great ease andflexibility, and much strain on the teeth and friction are avoided. E isthe main clampingjaw, constructed with lateral flanges j, a taperingprojection, 70, and a tongue, I. This jaw is somewhat of the shape of anobtuse angle, and fits in a grooved recess in the legs 1 and 2, as shownparticularly in Fig. 7. As there seen, the tongue I fits in a socket, i,in the end of leg 1, and the projection It extends outside of leg 2. mis a metallic washer placed on projection 70, and supporting a spring,m, which is held in place by contact with said washer and a lug, 0, onthe bearing c. F is the adj usting-screw clamp-plate, recessed andslotted at 10, so as to be detachably secured to the adjusting-screw Gr,and having a shouldered head, 1, which plays in the recessed leg 2 underthe jaw E, as shown in Figs. 1 and 10. The screw G is fitted in athreaded boss on the the end of leg 2, and serves to adjust the plate Fagainst a tub or elsewhere in securing the wringer for use. At the sametime the head of the plate presses against the under side of jaw E, andby compressing the spring a increases the pressure on the bearing 0,and, of course, the roll. The under surface of hearing 0 where thespring rests, and the surface of jaw E Where the lug 7c is, areparallel, and hence, when pressure is exerted on the spring, the washerm distributes such pressure evenly and equally through the spring, sothat the Wear on 'said spring will be alike in all parts. The casting A,with all its parts, including bearin gs and fenders, is made at oneoperation. So, also, is the bearing 0, and thus there is no necessityfor drilling, &c. The fender 4 is extended down to or beyond thevertical center of the lower roll, and thus prevents the clogging of therolls by clothes catching in it, and also prevents the consequent injuryto the clothes. H is the shaft of the lower roll extended to receive theoperating handle. The two sides of the wringer are exactly alike,except, of course, in the application of the gearing, and the only boltused in securing parts is the central bolt at s.

We are aware that three or more pinions have been used to transmit,uninterruptedly, motion to the rolls, but such gearing has not beenconnected by links, such as here shown. And, further, where four wheelsor pinions are used, three of them are movable and tend to producefriction and clogging, thereby renderin g the operation of the rollsuncertain and difficult. By our construction and arrangement of thegearing these difiiculties are avoided.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a clothes-wringer, the fixed pinions d e, movable pinions 0 f,links 9 h, and rolls B D, in combination with the jointed castings A G,substantially as and for the purpose described.

2. In a clothes-wringer, the bearing 0, constructed with flanged ears a,fitting over and embracing gudgeons b on casting A, as herein shown anddescribed.

3. The clamp-jaws E, constructed with flanges j and tongue I, incombination with legs 1 and 2, substantially as shown and described.

4. The bearing 0 of the upper roll in combination with the clamp-jaw Eand spring n, substantially as and for the purpose described.

5. The combination, with the bearing 0, spring a, and jaw E, of theplate F and adjusting-screw, substantially as and for the purposedescribed.

To the above specification of our invention we have signed our namesthis 21st day of September, A. D. 1874..
